I'm not sure how to check that. I initially thought that the provider (Bell) could have the feature blocked/suppressed for obvious reasons. I went back to the Bell store, but they said they don't block WiFi. They connected me with someone in their Handset Support who tried to help me for some time, but he also couldn't figure it out. In the end he thought that the OS needed an upgrade, as Bell's site was showing a slightly newer sub-release than the one in my phone. I downloaded it, but when trying to upgrade with Desktop Manager it said that there aren't newer releases. I'm puzzled...

Sometime bleeding edges release are recongized by the desktop manager innately. You can however install these updates onto your computer and then boot desktopmanager ...which should then say hey wait ..there's an update and prompt you to install.

If your behind a BES make sure you are updating from a corporate attached computer otherwise you will have to re-marry your blackberry (or rather IT will) and it can be a definite pita to get it done.
